Single-rack transmission bicycle capable of performing reciprocating variable circular motion

Abstract

The invention discloses a single-rack transmission bicycle capable of performing reciprocating variable circular motion. A transmission mechanism of the single-rack transmission bicycle can be used for bicycles, tricycles and other machines capable of achieving transmission through racks, and the single-rack transmission bicycle comprises a left pedal, a right pedal, a left pedal crank, a right pedal crank, a left pedal and right pedal alternating device, a single rack, a reciprocating variable circular device, a speed changing device and a reversing device. The reciprocating variable circular device converts reciprocating motion of the rack into circular motion, the speed change device can achieve high and low speed switching of the circular motion, and the reversing device can achieve reversing without matched actions such as lifting the rack. The bicycle is characterized in that up-and-down motion of the pedal is converted into reciprocating motion of the rack, and then the reciprocating motion is converted into circular motion efficiently with low noise through the reciprocating variable-circumference device; the gear and the rack can be sealed, so that oil stains are reduced, and sufficient lubrication can be realized; the problem of chain falling is avoided; a single rack is equivalent to a large fluted disc of a traditional bicycle, and the stepless speed change function can be achieved.

Description

technical field [0001] The present invention relates to a single rack drive bicycle with reciprocating variable circular motion, more specifically, it involves using racks, gears and other components to change the up and down motion of the pedal into the reciprocating motion of a single rack, and then the rack The reciprocating motion is converted into circular motion to drive the bicycle forward. This is a single rack drive that can replace chains, belts, and shaft drives. This single rack drive with reciprocating and variable circular motion can be used for Bicycles, tricycles or other machinery that can use rack drives. Background technique [0002] Many ways of converting circular motion to reciprocating motion can now be searched, so it is not difficult to realize the transformation of circular motion into reciprocating motion; but the way of converting reciprocating motion into circular motion often has certain defects that can be found, for example: 1. During the swi...

Problems solved by technology

[0009] The purpose of the present invention is to solve the problems in the prior art that the chains are easy to fall or even break, and the chains exposed in the air are easy to be dirty and rusted, resulting in transmission loss, etc. To solve technical problems such as low efficiency, provide a transmission scheme that can replace the circular rotation of the chain and pedals in bicycles. It uses a single rack to replace the chain, and replaces the circle of the traditional pedals with the up and down alternate motion of the pedals. Movement, which converts the up and down alternating motion of the pedals into the reciprocating motion of a single rack, and then converts the reciprocating motion of the single rack into circular motion, thereby driving the bicycle forward.
